What’s happening on the ground

Local officials blame at least 38 deaths and many more injuries on the storm, which has inundated parts of the Houston area with more than three feet of rain. In some places, totals surpassed 50 inches, setting a record for the continental United States. And, in Harris County, which includes Houston, up to 30 percent of the land had flooded, according to Jeffrey Lindner, a meteorologist for the Harris County Flood Control District.

While the storm began to release Houston from its grip on Wednesday, it continued to wreak havoc east of the city: “Our whole city is underwater,” Derrick Freeman, the mayor of Port Arthur, Texas, said on Facebook early Wednesday.

Harvey is now hitting southwestern Louisiana, too, where storm surge warnings and watches are in effect. Here are some maps of its path and destruction.
